Jack Daniel’s is produced in Lynchburg, Tennessee, by the Jack Daniel Distillery (currently owned by the Brown-Forman Corporation). The flagship brand Jack Daniels Old No. 7 is produced in much the same manner as bourbon, from a corn heavy mash and aged in new charred white oak barrels. However, the Jack Daniel’s distillery has always resisted the use of the bourbon classification, and instead prefers to label their spirit as Tennessee Sour Mash Whiskey. In the advertising and upon their website, the company highlights the fact that Jack Daniels Whiskey undergoes a filtering process (not typically used by bourbon producers) known as the The Lincoln County Process. This Process involves filtering the whiskey through a column of charcoal (or steeping the whiskey in charcoal chips) to remove unwanted flavours and contaminants prior to cask aging. The Jack Daniel’s Distillery produces its own charcoal pellets for the Lincoln County Process from sugar maple timbers. These charcoal pellets are packed into 10-foot (3.0 m) vats, where they are used to remove the impurities from the distilled Jack Daniel’s whiskey.
Gentleman Jack apparently undergoes the filtration process a second time as according to the Jack Daniel’s Website the whisky is Double Mellowed for Exceptional Smoothness.
